Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforcing approved authorizations structurally stops the runtime assignment of permissions that violate user intent.

AC-6 Least Privilege good match

Requiring least privilege limits the permissions the executing code is allowed to assign.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-05 partial match
blocks

Enforcing policy-defined permissions and least privilege directly prevents runtime permission mis-assignments.

PR.PS-01 partial match
blocks

Hardened configuration baselines and change control reduce the chance of incorrect permission settings during execution.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.18 Use of privileged utility programs partial match
degrades

Restricting privileged utility programs reduces the chance that such tools will incorrectly alter object permissions.

A.8.19 Installation of software on operational systems partial match
removes
A.8.2 Privileged access rights partial match
degrades

Privileged access rights management directly constrains the permissions a process may assign at runtime.

A.8.26 Application security requirements partial match
removes
A.8.28 Secure coding partial match
prevents

Secure coding practices can prevent the coding error that leads to incorrect permission assignment.

A.8.3 Information access restriction partial match
degrades

Information access restriction policies limit the permissions that executing code can grant or modify.
